Automation Quote Comparison 2026 — Align Scope Before Price

When automation quote comparison goes wrong, the cause is rarely a lack of technical judgment. It is usually something much simpler. The price gap between the three quotes on your desk reflects neither performance nor engineering capability. It reflects the fact that each vendor quietly drew a different line around what is included, and nobody noticed before the numbers were lined up side by side. This article is not about how to choose a particular machine. It is about a comparison template that works regardless of equipment type, and it focuses on one question. What has to be aligned before you are allowed to compare prices at all?

Why automation quote comparison never works on price alone

Price gaps are usually scope gaps, not performance gaps

Ask three vendors to automate the same process and it is entirely normal for the quotes to spread across a 1.5x to 2x range. The first instinct on the shop floor is a technical one. Maybe the expensive vendor is over-engineering it. Maybe the cheap vendor lacks the skills. But when you call each vendor in and walk through the breakdown line by line, the answer is almost always scope rather than technology.

The expensive vendor has included safety fencing, wiring, piping and foundation work inside its own scope of responsibility. The cheap vendor has excluded all of it as “arranged by the customer”. The machine specifications are nearly identical, and most of the price difference is simply the volume of installation work bundled in. In other words, the two vendors are pricing different products, while the buyer lines them up believing they are the same product. That is the classic way automation quote comparison breaks.

The awkward part is that this difference is hard to see on the quotation itself. Short notes such as “lump sum”, “to be discussed separately” or “supplied by customer” translate into gaps worth anywhere from a few hundred thousand to over a million THB. The price column is prominent. The notes column is not. And when someone builds a comparison table, the notes do not survive as columns. Only the prices do.

Four patterns where scope drifts

In practice, scope drift in automation bidding concentrates in four places. Closing these four first will already lift the accuracy of your comparison enormously.

First, whether ancillary work is included or excluded. Piping, wiring, power supply drops, air lines, foundation work, frames, safety fencing. None of this is the machine itself, so machine builders and system integrators treat it differently. Vendors with their own installation crews include it. Vendors without them write “separate”. Depending on the equipment, this can amount to 15% to 30% of the machine price.

Second, how witness testing, commissioning and adjustment are handled. How many people attend the factory acceptance test, and for how many days? How many days are budgeted for on-site adjustment after installation? How many operators are covered by training? This is all man-day driven, so any quote that does not state day counts will inevitably turn into an argument about additional charges later.

Third, whether spare parts and consumables are bundled into the initial contract. Some vendors include an initial spare parts set in the machine price. Others make you order it separately after start-up. The former looks more expensive up front, but the same cost appears eventually either way.

Fourth, the warranty period and its coverage. 12 months or 24 months? Parts replacement only, or does it include travel costs and engineer man-hours? Weekday daytime response only, or around the clock? Two quotes can both say “one-year warranty” and mean completely different things.

These four drift on every kind of equipment. For how responsibility boundaries are drawn on a specific project type, How to Choose a Robot SIer 2026 lays out where the line falls between buyer, integrator and manufacturer. This article sits upstream of that, covering the steps you apply in common before the equipment type is even settled.

Why the cheapest quote ends up costing the most

What actually happens when you pick the lowest number without aligning scope? The excluded work does not vanish. It simply moves onto the buyer’s plate. Worse, work that the machine builder could have coordinated alongside the equipment now has to be split out and ordered from separate contractors.

Split ordering tends to carry higher unit prices, and it multiplies responsibility boundaries. When the machine runs but does not synchronise properly with the transfer conveyor, the machine builder says it is outside their scope, and the conveyor supplier says it is a signal specification problem on the machine side. The buyer’s own engineering hours disappear into refereeing that argument.

Hours consumed this way never appear on an approval request or a comparison table, yet the burden on the plant is entirely real. Choosing the lowest bid and ending up more expensive in both cash and man-hours is a pattern that repeats itself across automation investment.

Identical-condition bidding is already standard in Japanese capital investment

What the Monozukuri Subsidy requires in writing

The idea of aligning conditions before comparing is not exotic. In Japanese domestic capital investment it is already written into public subsidy requirements and embedded in daily practice.

Under the Monozukuri Subsidy, items with a unit price of 500,000 JPY or more, excluding tax, generally require quotes obtained from 2 companies or more under identical conditions. What matters here is not only the vendor count. It is the qualifier “under identical conditions”. Matching the number of vendors is not the requirement. Matching the conditions is.

For used equipment, the bar is higher. Buyers must obtain competitive quotes from 3 companies or more of used-equipment distributors, with the model and year of manufacture stated. Used units vary enormously from one another, and without model and year on the page there is no common basis for comparison at all. Where competitive quotes are genuinely difficult to obtain, the practice allows the contract to proceed if a written justification for vendor selection is prepared.

What this framework establishes is that, when public money is involved, quotes obtained under different conditions do not count as a comparison at all. Put the other way round, the rules state plainly that two quotes prepared on different terms are not evidence of anything.

Overseas plants tend to lose this assumption

Staff who are perfectly used to this discipline in Japan often drop it after transferring to Thailand or another overseas site. There are several reasons. The enforcing pressure of a subsidy application is gone. Local suppliers have wildly different areas of strength, so putting them on the same footing is harder to begin with. Japanese, English and Thai are all in play and quotation formats never match. And with head office approval deadlines looming, someone builds a comparison table of price columns first and asks questions later.

But the underlying principle does not change at a border. If conditions are not aligned, there is no comparison. If anything, overseas sites need the alignment work more, because supplier business models differ more widely and commercial customs are less uniform.

The scope normalization template — a five-layer checklist that makes comparison possible

Defining the five layers

Telling vendors abstractly to “quote the same specification” will still produce five different interpretations. What works in practice is to split the places where cost arises into layers, and force every vendor to select one of three values for each layer — included, separate, or out of scope. Across the equipment-specific ordering guides published on the TOMAS TECH blog, the structure behind divergent quotes can be explained with the same 5 layers.

Layer 1, the core equipment, looks like the easiest thing to compare and is in fact where software licence terms hide differences. A licence that appears perpetual may carry a mandatory annual support fee, or may need to be purchased again when the solution is rolled out to an additional line. These terms often do not appear on a first quotation.

Layer 2, peripherals and ancillary work, is the layer with the widest price swing. Take the control panel alone. Building it in Japan and importing it, versus building it locally, changes price, delivery and lead time. That decision is worked through in detail in the Control Panel Design & Build Ordering Guide 2026.

Layer 3, engineering, has no physical deliverable, which makes it the layer most often flattened into a single lump sum. Getting a man-day rate and an assumed man-day count out of each vendor is the minimum condition for any comparison. For how the software side should be divided up, PLC Program Development Outsourcing is more concrete.

Layer 4, installation and start-up, comes down entirely to whether days and headcount are stated. A line reading “commissioning, lump sum” is not a promise of unlimited days. It means each vendor has assumed a different number of them.

Layer 5, the operating phase, is the classic omission from an initial quote. Compare without it and you get the TCO reversal described further below.

Putting every vendor onto a single sheet

Once the five layers are defined, the next job is to take each quotation apart and paste it back onto this one sheet. Before entering any money, fill in only the three values — included, separate, out of scope.

The moment this table exists, it is visually obvious that the three quotes are not describing the same thing. You are allowed to line up prices only once every cell in this table reads “included”.

Converting “separate” into money

Getting every vendor to “included” is the ideal, but some simply cannot do it given how their business is set up. In that case the buyer fills the gap by pricing the “separate” items themselves, either by taking competitive quotes from other contractors or by applying benchmark figures from past internal projects.

When doing this, build in the tendency for split ordering to carry a higher unit price than a single bundled order. The same safety fence costs more when the buyer orders it standalone from a third party than when the machine builder procures it as part of the package, because of the extra design coordination involved.

Comparing on total cost of ownership

Look at five years of total cost, not the initial contract price

Once scope is aligned, the next thing to align is the time axis. Comparing only the initial contract value is mathematically identical to assuming every vendor’s post-start-up costs are zero.

iFactory, which publishes an RFP template for equipment and automation vendor selection in manufacturing, structures capital equipment procurement around a five-year total cost of ownership broken into 8 categories, written out year by year. The 8 categories are as follows.

Having buyers fill in all eight categories by year, the same guide sets out the principle that “Lowest bid rarely wins; lowest TCO usually does” (iFactory). It also notes that a capital equipment RFP cycle normally runs 12–20 weeks.

Differences in contract structure distort the price ranking

The guide is especially insistent on itemised pricing. Bundling is not permitted, and equipment, installation, training, support and spare parts must each be quoted as separate lines.

Why forbid bundling? Because a bundled quote makes comparison physically impossible. If one vendor folds training into the machine price while another bills it as a separate post-installation service, putting their two “machine price” figures next to each other is meaningless. The only difference is how the contract was sliced, and whoever reads the ranking picks the one that looks cheaper.

Demanding itemisation is not a haggling tactic. It is a precondition for comparison to exist. Think of the five-layer checklist above as that same itemisation, restated in the working vocabulary of automation projects.

Worked example — Vendor B looks 39% more expensive and is cheaper over five years

Assumptions, all figures hypothetical

Every number from here on is an illustrative assumption and does not represent actual market pricing. Picture a single pick-and-place robot cell for the same process at the same takt time, quoted by Vendor A and Vendor B, with broadly equivalent equipment specifications from both.

The quoted amounts side by side

At this point the picture looks unambiguous. Vendor B is 900,000 THB more expensive than Vendor A, roughly 39% higher. Send a price-column comparison table up for approval and Vendor A wins.

Real cost after scope is aligned

Now add the buyer’s expected cost of arranging Vendor A’s “separate” items, bringing all five layers to “included”. Because these are split orders, each is assumed to run roughly 10% above Vendor B’s equivalent line.

Vendor A’s normalised initial cost becomes 2,300,000 THB plus 930,000 THB, or 3,230,000 THB. Vendor B already covered all five layers, so nothing is added and it stays at 3,200,000 THB.

The 900,000 THB gap visible in the quotes disappears the moment scope is aligned, and Vendor B comes out 30,000 THB cheaper. That is a difference of about 0.9%, which is effectively a tie. The 930,000 THB added to Vendor A amounts to roughly 40% of its 2,300,000 THB quoted total.

Extending to five-year TCO

Next, add five years of operating cost after start-up. Both vendors are now at 24 months equivalent warranty, so years 1 and 2 carry no maintenance contract fee, only consumables. Because the equipment is the same, consumables are assumed at 60,000 THB per year for both. From year 3 onward an annual maintenance contract applies.

Spreading that across the five years gives the following annual cost for each vendor.

Adding that operating cost to the normalised initial cost gives the five-year TCO for each vendor.

Over five years, Vendor A ends up 135,000 THB more expensive, a gap of about 3.4% against Vendor B. Vendor A appeared to be 900,000 THB cheaper on the quoted figures, and the ranking has flipped.

Note that the 170,000 THB booked in Layer 5, the warranty extension fee and the initial spare parts set, is paid at contract signing and is a different thing from the annual maintenance contract. Initial cost and annual cost are kept strictly separate so that neither is counted twice.

What this worked example actually shows

The point is not that Vendor B is the right answer. The example demonstrates three things.

First, the 39% gap on the quoted figures was a scope gap, not a performance gap, and it shrank to 0.9% the instant scope was aligned. Second, missing only Layer 5 out of the five is enough to produce a 135,000 THB reversal over five years, and on larger projects that reversal scales up proportionally. Third, making this comparison work required no advanced technical evaluation whatsoever. It required filling in a number wherever the word “separate” appeared.

The buyer writes the scope first

From collecting three quotes to handing out one sheet

Reading this far, you may feel it is a lot of work. It is. Taking apart quotations that have already arrived and re-aligning them by hand is genuinely heavy labour. But reverse the order and most of that work disappears.

Instead of gathering quotes and then normalising them for comparison, build the five-layer scope sheet yourself first and hand it to every vendor to complete in the same format. Then the quotes arrive already aligned, and building the comparison table is pure transcription.

The iFactory guide takes the same position, warning that a vague scope produces proposals that cannot be used, and requiring the buyer to define both the requirement specification and the itemised format up front. Three incomparable quotations are simply what happens when each vendor is left to interpret the boundaries of a vague request document on its own.

How to hand out the scope sheet in practice

Because you are only changing the order of operations, no special organisation is needed. In practice the flow looks like this.

• Write up the target process and its current problems on a single page. State takt time, target workpiece, operating hours and connection points to existing equipment as numbers.
• Build the five-layer sheet, marking items you absolutely require as mandatory and items left to the vendor’s judgement as optional.
• For each layer, provide fields that must be filled in with one of the three values plus, where included, the amount, the assumed man-days and the assumed number of days.
• Ask about warranty terms in dedicated fields, covering not just the period but whether coverage is parts only or includes travel and engineer man-hours, plus response hours and target response time.
• Require the annual maintenance contract price and the expected annual cost of spare parts and consumables to be quoted separately from the contract itself.
• Send the same sheet to every vendor at the same time, with a common response deadline and a common question period.

As a rule, share every question and answer with all vendors. The moment one vendor receives extra information alone, conditions are no longer aligned.

According to the same guide, a capital equipment RFP cycle normally takes 12–20 weeks. Working backwards from your head office approval calendar, the date on which you should start drafting the scope sheet is usually earlier than it feels.

When the process to automate has not been decided yet

Writing a scope sheet is hard if the target process itself is still open. In that case you need to sort out process selection before comparison begins. How to choose the target process and sequence the investment decision is covered in Using Automation Consulting 2026.

Four common pitfalls in automation competitive bidding

Pitfall 1 — deciding on price alone while neglecting technical fit and reference checks

Once the five layers are aligned and the totals sit close together, some buyers make the final call on decimal places. But price is not the only axis. Does the vendor have delivery experience with similar workpieces and similar processes? Will they show you a running installation? Can you call an existing customer and ask about uptime and start-up duration? None of this appears in the price column, and all of it comes back as a difference in start-up time.

Where possible, reference checks should reach beyond the contacts the vendor supplies, using the buyer’s own network as well.

Pitfall 2 — evaluating demos and proposals on vendor-supplied data alone

Cycle time and yield figures in a proposal are values measured under conditions the vendor prepared. Demonstrations are the same, often run with sample workpieces the vendor brought. Unless you bring your own real workpieces, your real variation range, and your real contamination and unit-to-unit differences, those numbers are not a forecast for your process.

Where feasible, hand the same real workpieces in the same quantity to multiple vendors and have them run the test. The principle of aligning conditions applies here too.

Pitfall 3 — comparing different models, model years and specifications on price alone

This problem appears as soon as used equipment or different grades of a manufacturer’s standard machine enter the candidate list. The reason the Monozukuri Subsidy demands competitive quotes from 3 companies or more with model and year stated for used equipment is exactly this. Unit-to-unit variation is large, and without model and year there is no basis for comparison.

Even with new equipment, if you line up machines with different payloads, different reach or different accuracy classes, of course the cheaper one is cheaper. Always give your comparison table columns for the main specifications, and where specifications differ, treat the candidates as belonging to different categories. In areas with high specification freedom, such as jigs and fixtures, this difference is even harder to see. How to pin down specifications is covered in Jig Design & Manufacturing Outsourcing 2026.

Pitfall 4 — forgetting warranty and maintenance differences in the comparison table

As the worked example above showed, warranty differences become material amounts over a five-year horizon. Despite that, comparison tables often stop at three columns — machine, installation, total. Warranty period, warranty coverage (parts only or man-hours included), treatment of travel costs, response hours, target response time, and annual maintenance contract price. Make these six permanent columns in your comparison table.

At overseas sites including Thailand, the physical distance to the service base is also a condition. A vendor with engineers stationed near Bangkok and a vendor flying in from Japan or a neighbouring country are not equally capable of delivering the same “next business day response”.

Equipment-specific criteria belong in the individual guides

Because this article is confined to the comparison procedure, it does not go into what to look for on any specific piece of equipment. Domain-specific issues surface as soon as you start filling in each layer of the five-layer sheet.

Where you are having a machine designed and built from scratch, the drivers of quotation divergence branch out much further. Specification freeze timing, handling of design changes and modification support after mass production start-up are organised in the Custom Machine Design & Build Ordering Guide 2026.

The comparison template itself is equipment agnostic. What belongs in each cell of the five layers is not. When you build a scope sheet, keep the relevant domain guide open beside you as you fill it in.

Conclusion

The first move in automation quote comparison is neither adding more vendors nor pushing for discounts. It is building the basis for comparison yourself.

Most price gaps are scope gaps, and the drift concentrates in four places — ancillary work, witness testing and commissioning, spare parts and consumables, and warranty terms. Break the project into the 5 layers of core equipment, peripherals and ancillary work, engineering, installation and start-up, and the operating phase, then make every vendor declare included, separate or out of scope for each. That alone makes comparison possible. Extend the view to a five-year TCO and the cases where a low initial price reverses become visible.

The single change with the largest effect, though, is the reversal of order. Do not collect quotes and then align them. Build the five-layer sheet first and hand it out. Simply carrying the identical-conditions assumption, already codified as a subsidy requirement for domestic capital investment in Japan, into automation investment at overseas plants transforms the quality of the comparison.

Frequently asked questions

How many vendors should I ask for quotes?

The Monozukuri Subsidy calls for 2 companies or more as a rule for items priced at 500,000 JPY or more excluding tax, and 3 companies or more for used equipment. In practice, around three vendors is a workable number for a new automation project. Two gives you too little to judge on, while going beyond five causes the workload of Q&A handling and comparison to spike, which ironically makes it harder to keep scope aligned. What matters is not the vendor count itself but whether every vendor is answering under identical conditions. If only one vendor can handle the work, it is more practical to document your selection rationale than to force the count upward.

What should I do when one quote is dramatically cheaper?

Suspect scope before you suspect capability. Map the quote onto the five-layer checklist and identify which layers are marked separate or left blank. In most cases it is Layer 2 ancillary work, Layer 4 start-up man-hours, or Layer 5 warranty terms that has been dropped. Then recalculate, replacing the missing scope with the amount it would cost you to arrange. If it is still cheaper after that, require the vendor to state assumed man-days and installation days. If their man-day estimate is half of everyone else’s, either their understanding of the specification differs or they are budgeting on additional charges later.

How do I compare when models or specifications differ?

Avoid lining up prices on their own. First make the main specifications into columns of your comparison table — payload, reach, accuracy, takt time, assumed uptime, power consumption and so on — and run a first screening on whether each candidate meets your requirements. Machines that fail the requirements should be dropped even if they are cheap, or handled as a separate category. For used equipment, make model, year of manufacture, operating hours and overhaul history mandatory entries. Comparing prices for differing specifications in one table always ends with the cheaper unit being selected and the performance shortfall being discovered afterwards.

How do I factor warranty period differences into the comparison?

Align the periods first, then convert to money. For example, set a policy that everyone is brought to 24 months equivalent, and have vendors offering only 12 months quote an extension fee. Where no extension is offered, substitute the annual maintenance contract price and add it to the initial cost. At the same time, always confirm whether coverage is parts only or includes travel costs and engineer man-hours. Where travel is billed separately, assume an annual number of call-outs, convert it to money, and add it to the annual costs in your TCO. In the worked example in this article, both vendors were levelled to 24 months equivalent, and the maintenance unit-price gap of 30,000 THB over three years plus the travel-inclusive versus travel-separate gap of 75,000 THB over three years combine to a 105,000 THB spread across five years. The same words, “one-year warranty”, will not close a price gap unless coverage is aligned too.
